It shows Caroline Coyne’s bid to stop the bus minutes before she was battered to death.

Jurors at Nottingham Crown Court were told by the prosecution they will see the film in which the 28-year-old is seen waving at the bus in Nottingham shortly after 1am, then avoiding it as it passes by.

The court heard the driver of the out-of-service bus, who was taking staff home, swerved to avoid her.

An hour before she flagged down two special constables but they refused her a lift home.

He also denies false imprisonment with intent to commit a sexual offence and sexual assault on a 21-year-old woman on August 24 last year.

Stuart Rafferty QC, prosecuting, told the jury: “Two women were stalked and attacked late at night when each was alone and when each, the prosecution say, was identified as a potential target and when they may have been the worse for drink, making them vulnerable.”

Mr Rafferty said after the bus passed Caroline a resident woke to hear a woman shouting: “Get off me!” Her body was found in a nearby passageway the same morning.

A post mortem showed Caroline, of Top Valley, Nottingham, died from head injuries. Defence wounds on her hands indicated she had fought for her life.

Mr Rafferty said Caroline, mother of boys aged seven and five, was killed because she refused sex.

The court heard Powell thought the women would be easy targets because they had been drinking.

He allegedly told police: “I’ve no need to attack women because I can get them just like that.”
